A CPU is the electronic circuitry within a computer that carries out the instructions of a computer program by performing basic arithmetic logical, control and input/output operations specified by the instructions.
Knowing this, the answer is both C - That it coordinates the flow of instructions and data within computers, And A - That a control unit performs arithmetical and logical computations.
If you can only select one answer, I'd personally go with A.
The bastion host node is typically an influential server with better-quality security actions and custom software. It frequently hosts only a single request because it wants to be very good at whatever it does. The software is commonly modified, limited and not obtainable to the public. This host is envisioned to be the strong fact in the network to care for the system last it. Therefore, it often endures unvarying maintenance and audit. Occasionally bastion hosts are used to draw occurrences so that the basis of the attacks may be outlined. The bastion host practices and filters all inward traffic and averts malicious traffic from incoming the network, acting much like a gateway.
Answer and Explanation:
Backup control within the SAN is one which confines the backup to the SAN and does not pass it via corporate network.
Backup traffic within the SAN are easier to maintain and easily handled in contrast to the application server.
Backup in SAN is governed by such applications and mechanism which allows the easy handling of the backup traffic which is not provided by the application servers.
In case of occurrence of any failure, unlike application server, SAN provides smooth and fast migration
SAN holds data in cluster by the use of backup techniques not used in application server.
